Verify your PCB Layout

Verify the DRC Rules

The best place to find our detailed DRC rules are on our Service Page for the service you plan to use. Our Design Tool Help pages also contain some tips on how to enter these rules into many design tools.

Check Ground Planes

Different tools handle ground planes and copper pours differently. Some design tools require you to explicitly update them before the DRC checks and manufacturing outputs are valid!

Our Design Tool Help pages usually indicate when a tool may have problematic ground planes. Even if it’s not listed though, it’s always worth verifying. Let us know if we missed one!

Check all connections

It’s helpful to double-check all connections on your board.

Most tools have a concept of an “air-wire” or “connection line”, which provides a visual guide between two signals that should be connected, but aren’t. These are generally kept up to date via the DRC tool, or a dedicated “rats-nest” tool. While some designs will have 1-2 air wires where a jumper is expected, most designs should not have air-wires on a completed layout. If you see one, make sure to verify it, and connect it if possible.

If your tool doesn’t have “air-wires”, just pay close attention to your connections, and verify everything looks right and connects how you expect.

Version marking

A date or version number will help you keep track of visually minor but electrically significant changes as your design evolves. If you already have one, make sure to update it!

Check for traps

Every design tool has its own way of doing things. In some cases, the tools way of doing things may go against logical, expected behavior.

Since these depend heavily on the specific design tool, we recommend checking our Design Tool Help for unexpected traps. We’ve documented a number of traps that have affected our customers in the past.

Prepare manufacturing files

For Kicad and Eagle users, good news! You can usually skip this step, and upload the .kicad_pcb or .brd file directly.

Otherwise, you need to prepare the manufacturing files, commonly known as “gerbers”. This also depends heavily on the specific tool you’re using, so our Design Tool Help for your tool will be helpful. This is especially helpful for the Board Outline and Drill files, which are consistent issues.

For many tools, this step is a painful and error prone process. If something seems unusual, double check your settings, and try creating a new set of files.

Verify the Manufacturing Files

We generate previews for every file uploaded to our system. For many designs, these previews are sufficient to ensure that we’ve understood your design correctly, and that the design itself is correct.

For larger or more complex designs, we recommend using a gerber viewer to closely examine the gerber files. We highly suggest Gerbv, which is free, cross platform, and sees the files in a way that’s very similar to how our process does.

If something looks unexpected, unusual, or just plain wrong, check through our Design Tool Help or Troubleshooting pages. Odds are, we have something to help you sort it out.

If your stuck, feel free to contact us at [email protected], and we’ll help you get things fixed.

Place Your Order!

Post-order steps

Ordering your board is great, but that’s not the end quite yet!

Version Control + Backup

Inevitably, you’ll want to make improvements to your project. But, you’ll still need to work with with the board you just ordered. Consider how you’re planning to make it easy to access both the updated and the current version of your design.

While you’re at it, make sure your design is backed up somewhere safe, so you don’t have to repeat all this work!

Make a Personal Checklist

This list is great, but everyone has their own workflow. Keep track of anything else that surprised you, you almost forgot, or (if need be) actually forgot.
